Flow cytometry hydrodynamic focusing
WebIn flow cytometry, hydrodynamic focusing is the process aimed at solving hyperbolic velocity that causes cells/particles to move in a seemingly random manner (unfocused). Typically, this (random movement) occurs before the sample enters the flow chamber. Here, cells/particles in the fluid suspension (sheath fluid) move in a random fashion and ... WebFlow cytometry is a technology that simultaneously measures and then analyzes multiple physical characteristics of single particles, usually cells, as they flow in a fluid stream …
